COALESCE is often the best way to deal with nulls, but this column is numeric and a null must be treated differently than a zero. I guess I could convert it to character, translate the nulls to blanks and do some extra processing in my code. That would be a whole lot more work than just using a locally-defined null indicator field and moving that into the DS field. It's just a mystery why it won't allow the field defined in the DS to be the null indicator.
